WAY Systems, a company making it possible for merchants to take debit/credit cards using an adaptor for their mobile phones.

from their website:

WAY Systems’ Mobile Transaction Terminal (MTT™) is the industry’s first ‘out-of-the-box’ solution to hit the market, enabling global resellers to quickly provide merchants with a pre-activated wireless data service that is ready to process transactions via popular processors upon delivery.

Available through a worldwide community of Independent Sales Organizations, (ISOs), Agents, and partners network, WAY Systems’ MTT products and services are helping mobile merchants virtually anywhere their business takes them.
